Development of a Subjective Flutter Measurement Standard

This paper presents the history and the text of a new draft Subjective Flutter measurement standard being considered by IEEE as a replacement for the present -Flutter Content- standard (IEEE No. 193, ANSI Z57.1-1954). The Subjective Flutter measurement method is identical to the -weighted quasi-peak- method previously standardized by DIN (45 507, 1966) and CCIR (409-1, 1966), and now under consideration by IEC.
